Procedure

A solution of 50.0 mg (0.13 mmol) 2-hydroxy-4-methyl-2-((S)-6-oxo-6,7-dihydro-5H-dibenzo[b,d]azepin-7-ylcarbamoyl)-pentanoic acid and 18.6 mg (0.26 mmol) cyclopropanmethylamine in 1.5 ml dimethylformamid were cooled to 0° C. and 20 μl (0.14 mmol) triethylamine and 54.5 mg (0.14 mmol) O-(benzotriazol-1-yl)-N,N,N′,N′-tetramethyluronium hexafluorophosphate (HBTU) were added. Stirring was continued over the weekend at room temperature. Removal of the solvent by distillation and chromatography on silicagel with heptane/ethylacetate (gradient 19:1 to 1:1) yielded 10.0 mg (18%) (R/S)-N-cyclopropylmethyl-2-hydroxy-2-isobutyl-N-((S)-6-oxo-6,7-dihydro-5H-dibenzo[b,d]azepin-7-yl)-malonamide MS (m/e): 436.1 (M+H)+.
